Yes, these are the Ontarios. The Fortress has the hooked guard like the Hell's Belle and a 10 3/8" blade. The Gambler has a 9 1/2" blae and no hooked guard. Now, the Gambler has a 5" handle and the Fortress a 6" handle. That's what's got me guessing. I like the hooked guard of the Fortress, but wonder if my small hand might better fit the Gambler. And, perhaps, the Gambler might be slightly nimbler, another plus for a small-handed guy. I just wonder about which handle will fit me better. My hand is 6" long from wrist to tip of middle finger and 4 1/2" wide from edge of hand to edge of thumb with thumb along hand in a "salute" poise. This is my dilemma. Ultimately, curved guard as to take a backseat to a confortable grip. So, if anyone can help me out here, I'd really be a thankful man.
